Sexual vs. Asexual Reproduction
Sexual Reproduction of Plants
Flowers are the reproductive part of plants.
Structure of flower:
Reproduction in flowering plants begins with pollination, which is the transfer of pollen grains to the female part of a plant. Flowers can be pollinated either by insects or by wind, and these two types of flowers have undergone adaption to facilitate pollination.

Germination is the process in which a seed develops into a young plant.
A seed consists of three different parts:
Asexual Reproduction of Plants
Plants can reproduce asexually, either naturally (e.g. runners) or artificially (e.g. cuttings).
Some plants, such as strawberries, have long stems that grow horizontally along the soil surface. These stems are called runners, and they have buds and roots that can grow into new plants.
A piece of the stem or root of a parent plant can produce a whole new plant, when placed in a suitable medium. Stem cutting will produce a new root, and root cutting will produce a new shoot.
